  4. Evening guys, I originally had a broadcast signal converter that I could plug all my 8 and 16 bit'ers into and fed nicely into the VGA port on a 25" Philips monitor but unfortunately DHL in my local country have made sure I'm never going to get it back after sending it for repair. The signal converter allowed lots of different resolutions and aspect ratios and was virtually limitless in the signals it would accept. Here in Ecuador there are a huge amount of 15-17" CRT's and LCD's and virtually nothing with S-Video inputs or that will accept happily the PAL composite video that my 800XL is knocking out. I have tried a $20 S-Video/Composite to VGA converter which gave me nice multicoloured blurred text on everything that I plugged into it (including a Raspberry Pi). So I'm looking to connect to VGA, especially as I still prefer the look of CRT's for my vintage machines. So, rather than going UAV now, I'm looking at getting a Sophia Board. I've tried reading through the Sophia threads but struggling to get a clear answer to some queries before I start hassling Simius with an order. I could do with hearing some experiences of other users findings. Firstly, the Sophia Rev.B is shown as RGB. Is this directly compatible with VGA or would it feed into one of the Arcade RGB to VGA GBS8200 converters found on Ebay? I ask about this board in particular because I'm getting one for an Amstrad CPC 6128 and could probably build a switch to shift between the tow machines. Secondly, regardless of this going VGA directly, or through an RGB converter, do I need to determine the resolution when I order the Sophia? Some of the monitors here are 1024 x768 and others 1280x1024. Are these the correct aspect ratios to be as similar as possible to old CRT TV's that the Atari's would have plugged into originally? Thirdly, if I end up having to order the DVI version, presumably there's a 1280x1024 option available, will I get black bars on the left and right of my full HD monitor to keep the aspect ratio or is it more likely to stretch to the whole screen or black borders on all sides with a tiny image in the middle? Lastly, is Simius based in Europe, or in the US, as I need to find out the best method of getting it to me without using couriers? USPS tracked service is ideal, but if it's coming from Europe then I'd need to get it shipped to the UK first to be forwarded by Royal Mail. Apologies for the long post and multiple questions. If you've any further advice or help to offer (unused Sophia Board??) please let me know, and thank you in advance.
  5. From the album: INTV

    My custom Sears unit that I restored & modded w/ RGB and composite AV, plus a custom Inty arcade controller that I built using a Neo Geo X as a base & Grips03's PCB kit. I used a magic eraser to clean up the cream colored plastic, the backend was repainted, a paint pen was used to touch up the raised lettering and then the whole console was clear coated. A lot of time and work put into it all, but everything came out great!

  10. So for my study in electrical engineering I had to design a single pcb, but I actually ended up designing multiple. The first one was an RGB board for the Colecovision that converted the analog video signals into RGB. With the schematic I built it from being quite sketchy, I'll only share it if it delivers any decent results. The second PCB is one I'm a little more confident with. There used to be a board like it called the Zoe (kinda wanna call it the Joey), but it was apparently a tough one to get. I also didn't like the idea of soldering 10 wires to the PCB. My idea is to imitate what Tim Worthington has been doing with the NESRGB and 2600RGB boards, where the modboard sits in the socket of the IC it takes the signals from while still leaving the IC functioning the same. This method is more work, especially if the IC isn't socketed to begin with, but leaves a much more tidy result. I also went with SMD components over through-hole as this allows for a smaller PCB, although it may scare the hobbyist away from it. The three IC's will be tough, but the other components should be easily doable with a soldering iron. The board also houses an additional pin header to do a composite video mod, which will require soldering a single cable to the Intellivision's board. Considering this is just a 3 bit DAC (times 3) I also tried making it with Opamps, but wasn't succesful in simulating anything functional. I didn't want to include a negative voltage on the board to use different opamps, and couldnt get anything working with single supply opamps. I'm not an electrical engineer quite yet, so my attempts only take me so far.
  11. I recently acquired a CGL M5. Its a machine I've wanted since they first came out. I loved the design of the Sord M5, and even though the CGL version doesn't share the Sord's elegant "M5" logo, it wasn't very expensive and allowed me to explore the great "M5 Multi II" multi-game ROM made and sold by Charlie Robson. Now this post may be in the wrong forum. But you guys know TI hardware better than anyone, and the CGL M5 uses the TMS9929A VDP also found in European spec TI99/4As among many other machines. The M5 then converts the R-Y, Y, B-Y output to composite PAL. But my monitor is a North American Commodore 1084, and expects composite NTSC or RGB. I've looked around for a 9929A to RGB conversion schematic, and there are a few, including the one linked in this document from a Sega SC3000 forum: http://www.smspower.org/forums/2325-RYBYYOutputFromSC3000VDPTMS9929 But I also see that some people have tried this approach and met with mixed results, including one ColecoVision owner who it seemed may have fried his machine in the effort (see post 26) http://atariage.com/forums/topic/110598-colecovision-av-out/page-2 This guy has a neat looking board that it seems would make pulling RGB from the TMS9929A straight forward, and has generously shared all the schematics and build files, but since I have never had a board made before I am way out of my depth on this one: https://hackaday.io/project/13056-tms9929a-rgb-and-component-adapter So another approach might be to convert the CGL M5 to use a TMS9918A instead? Can that be done? From an evening spent looking at websites, it seems I might be able to remove the 9929A and insert the 9918A. Leave pins 35 and 38 NC, and then drive pin 36 directly to the RCA jack. I'd need to replace the oscillator too to get the right color signal for NTSC, and probably burn a Sord NTSC BIOS so that the unit reports itself as NTSC to those games that depend on timing. So how insane is the replacement plan? Would it work in theory? Assuming there isn't something else in the Sord's design that prevents it? Can you tap composite NTSC right off pin 36 of the VDP? What else would I need? Diodes? Resistors? And if these questions are worthy of a face palm, should I just go hunt for a native NTSC Sord model? I can also lug my Sony PVM out of the closet which has PAL and NTSC Composite and S-Video, but doesn't have RGB, so the Amiga and ST displays look awful. Thanks for any pointers.

  21. Up for sale are the citrus3000psi RGB boards for the Colecovision/ADAM. These boards are designed to be soldered to the bottom of the VDP and provide RGBS to an output connector of your choice. To properly calibrate these boards, 3 onboard POTs are used to adjust each color individually. Please note that to properly calibrate the board, you MUST use an oscilloscope. If you do not calibrate with an oscilloscope and choose to adjust by eye, please note that any compatibility issues, damage, or world ending results via the summoning of Cthulu are solely your responsibility. Each kit is sold as a DIY and fully assembled/tested before shipping. If you receive a board and have issues, please contact me. If the issues are found to be related to misuse or improper installation, you are on your own. If there appears to be a defect in manufacturing, I will work with you towards an amicable resolution. No output connectors are provided, except with install service. Output connectors can be whatever you wish but the cables themselves must be pass-through, ie no capacitors or resistors installed. If you need assistance with purchasing cables or output connectors please reach out and I can answer your questions. Each board is $30 shipped in the Continental US (CONUS). If you do not feel confident with the installation or would prefer to have it installed for you, I will be providing install services with oscilloscope calibration of the board. Cost of this service is $80 including the board, but not including return shipping.
  22. Wanted to get a head start on seeing what other Geneve users would like to see for packages offered for the SCART-Genie.
  23. I just ran across this on Twitter, a new DIY ColecoVision RGB board by Citrus3000psi. Still in prototyping phase but will hopefully be coming out soon, after some more testing. This might be a nice alternative to the F18A for DIY'ers. Check out @citrus3000psis Tweet: https://twitter.com/citrus3000psi/status/953443909501444096?s=01 Now if someone would come out with a better Intellivision RGB board, I'd be on cloud 9!
  24. I have a Magnavox 8CM515 monitor that I would like to use with a Genesis or SNES. However the analog RGB input has H and V sync while my game consoles have composite sync. Does anybody know if the 8CM515 will work with composite sync? Do I have to make a sync separator? What about the Commodore 1902A? I swear it looks like the same monitor from the back.
  25. Hi guys, I would like to know your experiences with Monitors/Displays for running your TI-99, be it the US version (Composite) or the (European) PAL version using the YPrBr, or via the french RGB modulator RVB PHA 2037. Also I would like to know whether anyone tweaked his US console with a TMS9928A to get YPbBr out of it? It looks to me this is the best video chip to maintain the original desired speed of 60 Hz but getting the video signal via 3 component lines. The official TI branded 10" monitor is nice, I am missing the option to have RGB or YPrBr input. Even though there is supposed to be a PAL Version, that is nowhere to be found. I know about the F18A as video chip alternate with VGA output, I have two at home, however I am aiming for one setup now running the original experience. Sprites look so much more organic if there is Scanlines. In regards to the Monitor, I read a lot about Sony PVM CRT (Sony Professional Video Monitors) being the ideal displays for Retro Gaming since they don't upscale or screw up the video by believing it's interlaced content. Their geometry and quality is supposed to be outstanding. And from watching videos running RGB modded game consoles I can only agree with them. Sony PVM means they were not meant for the Consumer market but for the Professional market and therefore super expensive. Above that level is ever a higher class called Broadcast Video Monitors (Sony BVM). Those have even higher quality standards. Those devices can be feeded via Composite Input but you should aim for YPbrBr or RGB video as Input for those. Here is some example video, there are lots out there, it's kind of hard to capture the quality of those devices since they are from CRT (interlaced) running 60fieldsPerSecond and Youtube has 30fps: People talk a lot about 240p meaning, even though the console renders two fields via it's analog video out ports the content of those two fields match one progressive frame. A lot of TVs/Upscalers treat the ouput wrongly as 480i and starting to process the video with which then the problems starts. BR Klaus
